The Etherlab EtherCAT Master does appear to be a normal GPL project. I think that the difficulty is that the _use_ of the EtherCAT standard is governed by an additional license: http://ethercatmaster.berlios.de/files/EtherCAT_Master_License_Agreement.pdf This might actually mean that we are free to ship a HAL driver that links to the (GPL) Etherlab EtherCAT master, but that any users linking their system to actual EtherCAT hardware would become liable to the license above. Is this any different to the situation of linking, via EtherNET, to a Windows PC from a Linux PC? There is an (old) thread on the subject here: http://lists.etherlab.org/pipermail/etherlab-users/2008/000243.html IANAL. And the whole licensing thing irritates me. -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ October Webinars: Code for Performance Free Intel webinars can help you accelerate application performance.
